Description Adam Mariš 2017-06-26 13:09:50 UTC 
An integer overflow vulnerability in the ptp_unpack_EOS_CustomFuncEx function of the ptp-pack.c file of libmtp (version 1.1.12 and below) allows attackers to cause a denial of service (out-of-bounds memory access) or maybe remote code execution by inserting a mobile device into a personal computer through a USB cable.
